Objective: Pervious RT-PCR results revealed the possibility of effective regulation channel of Xiaoyao San in treating rats of syndrome of liver invading the spleen. This experiment was designed to explore CIS rats’ immunohistochemistry findings in hippocampal subregion CA1 and amygdaloid subregion BLA after suppressing both amygdaloid AMPA receptors by microinjection of CNQX. To compare Xiaoyao San group with CNQX group, and to analysis of these findings may prove the possibility of effective regulation channel of Xiaoyao san treating this syndrome. Methods: 75 male SD rats were randomly divided into 5 equal groups: normal group, CIS group, sham-operation group, CNQX group and Xiaoyao San group. The number of GluR2 positive cells in hippocampal subregion CA1 and amygdaloid subregion BLA in these 5 groups were examined by immunohistochemistry test. Results: Compared with control group, the number of GluR2 positive cells decreased in hippocampal subregion CA1. Statistical analysis showed that no difference existed in control, CNQX and Xiaoyao San groups in CA1 region. Except CNQX group, tendency of changes were contradictory in BLA and CA1 region. In addition, the least in BLA in CNQX group. This finding revealed that Xiaoyao San may act the same as CNQX, thus Xiaoyao San afforded effective protection against this depression syndrome through suppression of both amygdaloid excitability. Conclusion: The balance coordination between hippocampus and amygdala may be the key in transformation from adaption to damage in a state of stress, was one of the central mechanisms of liver governing smoothing qi flow (LGSQF) on regulating the stress. Xiaoyao San may effectively regulate the balance of the excitability of hippocampus and amygdala. This hypothesis may reveal the regulation channel on Xiaoyao San affording effective protection against liver invading the spleen syndrome.

Tujia ethnic medical science is an important sub-discipline of China's ethnic medicine system, which has rooted in major Tujia ethnic area such as Hunan, Hubei, Guizhou and Chongqing. It has its own theory, medication characteristic and experi-ence towards ethnic drugs. Particularly, in medication incompatibility, it has formed the principle of thirteen or fourteen incompatible medicament of traditional Tujia ethnic drugs, which play a certain role in guiding the usage and compatibility of tens of thousands of herbs. Focusing on the incompatibility that is abided by Tujia medical workers, the essay makes a textual study on the origin of herbs and conducts a preliminary study on the theoretical basis of thirteen or fourteen incompatible medicaments in terms of four properties of drugs and toxic and side-effect by reference to the records on nature and flavor and effectiveness, with a view of providing a preference to improve the incompatibility theory of traditional Chinese medicines and new ideas to further studies on the development and application of traditional ethnic drugs.

Malignant tumor is the common disease that threaten severely to people's health. Formulae of traditional Chinese medicine (FTCM), as the major component of traditional drugs, has played more important role on the prevention and cure to tumor. The Folkman's theory that tumorous growth depends on tumor neovascularization has been confirmed so many years, so to inhibit the tumor angiogenesis, is an important path to treat tumor. The research of FTCM to antagonizing tumor angiogenesis in our country has been started more lately. Since it has been reported some FTCMs can inhibit angiogenesis, and it also exists many problems. The article summarized the correlated research of FTCM to antagonize tumor angiogenesis for the past several years, and according this, analyzed, stated and commented to the problems, countermeasures, development and direction of PTCM to antagonize tumor angiogenesis.

OBJECTIVETo investigate the effects of hydroxy safflor yellow A (HSYA) on the expression of bFGF protein and MMP-9 mRNA or protein of transplantation tumor of gastric adenocarcinoma cell line BGC-823 in nude mice.

METHODThe BGC-823 cells were subcutaneously injected into the right anterior armpit of BALB/C nu/nu nude mice, and the animal model of transplantation tumor was established. The experimental groups were treated with HSYA at concentration of 0.056 and 0.028 g x L(-1) and cyclophosphamide at 2 g x L(-1), or with physiologic saline. The tumor inhibitory effect was observed, and the mRNA expression of MMP-9 of transplantation tumor was detected by real time-fluorescent quantitation PCR and the protein expression of MMP-9 and bFGF were detected by enzyme linked immunosorbent assay.

RESULTThe IR in the group with HSYA at the concentration of 0.028 g x L(-1) is higher than in the group with normal sodium. After treatment with HSYA, the mRNA expression of MMP-9 has significant difference at the concentration of 0.028 g x L(-1) as compared with physiologic saline-treated group (P < 0.05), but the protein expression of MMP-9 and bFGF is obviously less than that in the physiologic saline-treated group (P < 0.05).

CONCLUSIONThe possible mechanism of HSYA in given concentration to antagonize tumor angiogenesis may be related with inhibiting the protein expression of MMP-9 and bFGF or the mRNA expression of MMP-9 in tumor tissue to reduce the degradation of blood vessel basilar membrane, and to restrain the migration of blood vessel and decrease the tumor vascularization.

OBJECTIVETo investigate the effects of Hydroxy Safflor yellow A (HSYA) on the growth of blood vessel of transplantation tumor of gastric adenocarcinoma cell line BGC-823 in nude mice and its underlying mechanism of antagonizing tumor angiogenesis.

METHODThe BGC-823 cells was subcutaneouly injected into the right anterior armpit of BALB/C nu/nu nude mice and established the animal model of transplantation tumor. Then nude mice were divided into 4 groups at random: model group, control group, high or low dosage of HSYA group. The model group were treated with normal sodium by intraperitoneal injection, HSYA groups were treated with HSYA at concentration of 0.056 g x L(-1) and 0.028 g x L(-1) by intraperitoneal injection, and in these groups each mouse was injected 2 times everyday with 0.2 mL by 4-6 hours interval. The control group were injected in enterocoelia 1 times every 2 days starting from the third day with cytoxan at 2 g x L(-1). 20 days later, the volume and weight of nude mice were observed. The pathological change of tumor tissue was observed under optical microscope. The mRNA expression of VEGF and bFGF of transplantation tumor were detected by real time quantitative PCR.

RESULTThe volume (607.42 +/- 252.96) mm3, weight (0.88 +/- 0.14) g of transplantation tumor, the mRNA expression level of VEGF 0.49 +/- 0.13 and bFGF 0.60 +/- 0.48 are reduced significantly after treatment with HSYA at the concentration of 0.028 g x L(-1) compared with physiologic saline-treated group (P < 0.05 or P < 0.01). The tumor pathological angiogenesis of HSYA group is also less obvious than the normal sodium-treated group.

CONCLUSIONHSYA in given concentration can inhibit the growth of BGC-823 transplantation tumor, and decreasing the mRNA expression of VEGF and bFGF, which suggests that inhibiting tumor angiogenesis may be one of the mechanisms of HSYA antagonizing tumor.
